Connect 220 Vac power. The power lamp (far left
of the orange color E-Stop button) should light,
unless circuit breaker QF in the electrical box has
tripped.
Be sure the E-Stop button has not been pushed in
(it should pop out when twisted clockwise).
Shift the motor control lever DOWN. The spindle
should turn forward, counter clockwise, viewed at
the chuck (nose) end.
Check the emergency function by pressing the E-
Stop button. The motor should stop.
If this doesn’t
happen, the E-stop function is defective, and
needs attention.

when the guard is swung up.
Check that the belt cover interlock stops the motor
when the belt cover is removed.
Check that the footbrake stops the motor.
Return the motor control lever to OFF, mid-travel.
The motor should stop.
Shift the motor control lever UP. The spindle should
